- Added memory debugging features to log heap usage and fragmentation recovery for MQTT clients.
- Introduced `recreateMqttClientsForFragmentationRecovery()` to manage MQTT client lifecycles and reduce memory fragmentation.
- Updated critical memory checks to log detailed heap statistics and active MQTT client counts.
- Included new debug logging for memory status every 60 seconds when memory debugging is enabled.
This update aims to improve stability and performance in memory-constrained environments.
- Main broker: only allocate _mqtt_client when custom broker configured
(analyzer-only saves one PsychicMqttClient). Reconnect main broker after
forced disconnect with 30s throttle; set last_attempt on disconnect so
throttle applies and avoids reconnect storms on flaky WiFi.
- Analyzer clients: call disconnect() when WiFi transitions to disconnected
so ESP-IDF frees MQTT buffers (it does not free on WiFi drop). Reduces
fragmentation and Max drop after disconnect/reconnect cycles.
- get wifi.status: report WiFi uptime (Xd Xh Xm Xs) when WITH_MQTT_BRIDGE.
Track connect time in bridge; backfill when already connected at first check.
- get mqtt.status: show msgs on/off, broker (connected/disconnected/n/a),
analyzer US/EU (connected/disconnected/off), and queue count.
Note: PsychicMqttClient change (register event only on first client creation)
belongs in the library repo if committed separately.
- Updated comments to specify that the Dispatcher owns the packet memory and should handle freeing.
- Removed unnecessary calls to free queued packets in the MQTTBridge, ensuring only references are discarded.
- Enhanced code clarity regarding packet lifecycle management in the end and processPacketQueue methods.
- Introduced `getPacketsRecvErrors()` method in `Dispatcher` to track receive errors.

- Adjusted `RadioLibWrappers` to override `getPacketsRecvErrors()` for consistency.
When DISPLAY_CLASS is defined via build flags but HELTEC_LORA_V4_OLED
or HELTEC_LORA_V4_TFT flags aren't set, include SSD1306Display.h as
fallback. This fixes compilation errors for environments like
heltec_v4_repeater_observer_mqtt that extend Heltec_lora32_v4 directly
and set DISPLAY_CLASS=SSD1306Display.
